To all whom it may concern:

Be it known that I, HERMAN Somzonnsn, a citizen of the United States, and resident of Quincy, in the county of Adams and State of Illinois, have invented a certain new and useful Poisonous Compound for Rats, &c.,

half cent per day, and estimating one rat to each person, the sum of one hundred and eighty million dollars er year is lost to the country by the depre ations of such pests. Also it has been determined that one rat will consume fifty pounds of grain in a year, which involves considerable loss to the farmers.

.Therefore, it is the aim of the present invention to provide a poisonous compound used on wheat for killing rats and like animals. It being a further aim to place a certain quantity of wheat, saturated with this improved compound in a saucer or other receptacle and place it where it is convenient to the animal to be exterminated.

Further, it is an object of the invention to compounds, poisonous substance or mixture for rats, com rising arsenic trioxid, sixteen grains, stryc nin alkaloid, sixteen rains, glacial acetic acid, 99% asixteen mlnims) uid extract elsemium, alf ounce, and fluid extract d1 'talis, half ounce.

In compoun in this poisonous mixture, the strychnin alka oid is first dissolved in a requisite amount of water to ther with the acetic acid, and subsequent about four ounces of hot water are adde The arsenic trioxid is then dissolved-in hot water and then the whole composition is dried by heat at a temperature of 212 degrees Fahrenheit.

The mixtures of strychnin alkaloid and hot water and the arsenic and hot water are then thoroughly mixed together, and to this compound the fluid extract gelsemium and the flu1d extract digitalis are added. The entlre mlxture is then thoroughly agitated. The wheat, rye, barley or other grain (substantially sixteen ounces) is then saturated with the compound, and a requisite amount is'placed in a receptacle to be arranged convenient to be reached by the rats or other animals to be exterminated.

It is obvious that the com und may be m xed in larger quantities, t ejngredmnts being proportionately increased.

It is obvious that this compound contains certain proportions of poisonous ingredients and furthermore, the sale of poison is always attained with great risk, therefore, when this compgund is manufactured and sold, 1t is to borne in mind that this compgund or poisonous preparation must not kept in places with medicine or food, so as not to contaminate the same.

The invention having been set forth, what is claimed as new and useful is 1. A poisonous food for vermin consisting of grain soaked in a solution formed b combimng arsenic trioxid, strychnin a aloid, glacial acetic acid, fluid extract gelsemium, and fluid extract digitalis.

2. An animal oison, consisting of grain soaked in a solution formed by first dissolving strychnin alkaloid in a requisite amount of hot water together with acetic acid and fluid extract gelsemiumincluding hot water
